"The essence of mathematics lies in its freedom."
Those who deny freedom to others, deserve it not for themselves; and, under a just God, can not long retain it.
生活的美丽在于,虽然我们不能撤销已经发生的事情,但我们可以看见它,理解它,从中学习并改变。因此,每一个新的时刻都不应浪费在后悔、内疚、恐惧或愤怒中,而应花费在智慧、理解和爱中。
"Trust is the foundation of any successful organization, and it must be earned every day."
